Letters Patent No. 99,671, dated February 8, 1870.

IMPROVEMENT IN SHIPPING AND UNSHIPPING--HOOKS- The Schedule referred toin these Letters Patent and making part of the'same.

To all whom it may concern Know ye that I, NOAH HAVERMALE, of Canton, inthe county of Fulton, and State of Illinois, have in.- rented a new anduseful Shipping and Unshipping- Hook, for hoisting heavy weights, andinstantly dropping them at any desired elevation; and I do hereby'declare that the following is a full, clear, and exact description' ofthe construction and operation ot' the same, reference being vhad to theannexed drawings, making a part of this specification.

"lhe nature ol' my invention consists iin so arranging and attaching asen'es of levers to a draught-bar, connected to the power, and on whichhangs the resistance, that the weight may be easily attached anddischarged at will.

'.lo enable others skilled in the art to make and use my invention, Iwill describe its construction and operation.

0f suitable metal, of proper size and strength, I make the draught-barA, having an eye in the upper end, to receive a hook, B, coupling it tothe power.

About three inches from the top a stationary arm,

0, is fixed to the side of the bar, at aright angle, and

having a pulley,'D, near its outer end.

Directly under this arm is E, a mortised projection ofthe bar, and thelower end of A is widened on the same side, and ymortised to receive thelever-hook F, pinned therein, and which passes through to the rear 1hrenough to receive the ring G, attached to the weight or resistance H.

The front end of the leverF enters and is pinned to a slotted ormortised end of the jointed lever I, whose upper end is secured in themortise at E.

A set-screw, J, working in the draught-bar, becomes a bearing for thejointed lever I, when the machine is raising a weight.

hastened to the jointed lever is a cord, K, which ,at the highestelevation.

of bar.

The machine is so made, that when the power and weight are coupled, asshown in the drawing, the back end of' the lever F inclines toward thedraught-bar, and the `jointed lever I bears inwardand rests on the screwJ.

`It' this machine is to raise a heavy weight, such as a pile-driverhammer, the hook B is inserted, and the lever I placed in Vthe ring ofthe hammer. As the power is applied, the ring draws toward thedraughtbar, because the upper edge ofthe lever F is a plane, inclined tothe bar.

As the weight is drawn up, the cord K rises with the tackle, and is longenough to reach to the ground By-drawing on theeordK, so that the outerangles of I become acute, the weight at once throws up the lever F, (asshown by red lii1es,) and unships itself.

This unshipping can be do'ne at any desired height of hammen'by pullingthe cord K. lf the height of elevation is determined, the weight isunshipped at that point, by tying the cord K, at the proper length, tothe frame which supports the main line and forms' the guides to thehammer.

What I claim as my invention, and desire to secure by Letters Patent, is

The construction, arrangement, and combination oi' the several parts,lettered A, G, D, E, F, I, J, K, and L, each constructed, and arranged,and combined, substantially as hercinbefore set forth, as and for theuses and purposes herein named, and I expressly disclaim' all otherparts and uses.

NOAH HAVERMALE.
